To all whom, it may concern.'

e it knownv that I, GEORGE C. ABBE, a citizen of thel United States, residing in Lansdowne, county of Delaware, State of Pennsylvania, have invented certain Imrovements in Locomotive-Frames, of which the followinglis a specification.

. My invention relates to certain improvements in frames used in connection With locomotives, especially of the electrical t-ype.

The object of my invention is to provide a frame which will not break at the angles. This object I attain by extending the frame above the cent-ral line and forming a truss; the truss being so designed that it Will not interfere with the springs of the equalizing ear.

In the accompanying drawings :#Figure 1, is a side view illustrating my side frame for locomotives with the equalizing gear and other parts in outline; Fig. 2, is an enlai-ged sectional view on the line 22, Fig. l; and Fig. 3, is aview showing a spiral spring subst-ituted for the semi-elliptic spring illustrated in Fig. 1.

A is the side frame of the locomotive having a main chord a, a lower chord al, and an upper chord a2.

5 b are the pedestals extending from the main chord to the lower chord and adapted to these` pedestals are the boxes B, of the ordinary type, in which the axles C are mounted.

Usually, the frame consists only of the main chord a and the -lower chord a1 with the connect-ing members, but it has been found that in many instances the frame will break atthe angles unless it is made of such a design that it will be cumbersome, but by forming a truss member above the normal line of the frame, I am enabled to make the frame perfectly rigid and to proportion it so that it will be comparatively light; either end beine' capable of' being raised without the liability of breaking any of the parts. The truss member, in the present instance, consists of the upper chord L and diagonal members (Z, forming triangular openings, as clearly-shown in Fig. 1. In the triangular openings7 directlyabove the pedestals b are LOCQMOTIVE-FBAME.

mounted the springs E of the equalizing gear. These springs are of the semi-elliptic type, as illustrated in Figs. 1 and 2, and the strap e of each spring rests vupon a block e1 which bears upon the top of the box B.

The springs may be separately coupled to the frame, or they may be connected throu h a beam E1 .and links e2, as illustrated. The s rings are located in the triangular spaces a ove the boxes and the straps connecting the springs to the frame, or other members 0f th equalizing gear, extend on each side .of the said frame.

openings in the diagonal members of't-he` truss, bu-t I prefer the construction illustratedin Figs. 1 and 2.

I claim:

1. An integral side frame for a locomotive having a continuous main chord and an interrupted lower chord; pedestals connecting thesections of the lower chord to the main chord; and a continuous upper chord and members connecting the upper chord to the main chord.

2. The combination of an integral side chord to the main chord, both chords being name to this specification, in the presence of abov the axle o oflcningband a, lower two subscribing witnesses. chor interrupbe V t e ax e ox o enngs;
